[PATCH BlueZ v2] Fix remove temporary link key for No Bonding

[Dmitriy Paliy <dmitriy.paliy@nokia.com>]

This fixes regression caused by 33cdfcb0fabcfb5260953a13ae277b5abe9a322d.
Temporary link key should be removed after device is disconnected if
bonding information is not stored in file system.

Currently, the key is deleted only when paired device is removed, or
adapter is powered off. In case of No Bonding authentication, device is
not paired after disconnection, which results in link key left in memory.

On the other hand, device is not necessarily removed after disconnection
that also leaves unneeded temporary link key in memory.
